IMPROVEMENT IN CAR-COUPLINGS.

Specification forming partof Letters Patent No. 135,871, dated February1l, 1873.

,To all whom it may concern:

Be it known that I, LIsToN B. WILSON, of Caldwell, in the county ofNoble and in the State of Ohio, have invented certain new and usefulkImprovements in Oar-Couplings; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawing and to the letters of reference marked fthereon making a part of this specification.

The nature of my invention consists in certain improvements upon thecar-coupling for which Letters Patent were granted to me N ovember 26,1872, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionapperta-ins to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Q Figure 1 is a perspective view, showing the 'end of a car with mycar-coupling attached thereto. Fig.l 2 is a longitudinal verticalsection of the draw-head. `FigfB lis a horizontal section of the same,and Fig. 4 is a perspective view of the movable bar in the top of thedraw-head. e

A represents the platform of a railroad car, in or under which is thedraw-head B. The interior of this draw-head is constructed, as shown inFigs. 2 and 3, with vertical convex walls a a on the sides, and aconcave back, b., Across the top of the draw-head is a slot extendingdownward in the sides of the head Vto receive a shaft, d, to which isattached a wing, c, and abovel theV same, in the slot of the draw-head,is placed a bar, D, with spring e on its under side, the bar being heldin place by a button, f, the same asA described in my former patentabove referred to. The

-endsof the bar D extend beyond the sides of the draw-head, and havedownward-projecting flanges on its ends, as shown in Fig. 4. The objectof the spring c is to hold the shaft and wing down, and yet at the sameAtime allowthem to play upward when needed. By the present constructionof the bar D the vstrain on-the spring e will, after the, shaft c hasrisen a certain distance, be taken up by the ends of the bar, and henceany liability to breaking the same entirely obviated. Gr represents thecoupling-bar provided at each end with a beveled point or head, h,forming shoulder i, against which the wing C works to couple the cars.The entire bar Gr between the heads or points h h is slotted longitudinally, so that it can be used in place of the ordinary link, orwhen a car with my coupling should be used with a car` having the commonlink-and-pin coupling. The lowe.face B of the draw-head is inclineddownward at its front from the bearing-point a', and is also inclineddownward sharply from the 'rear of this bearing-point, so that when thelink is in the head, with one of its enlargements in the` rear of thegate C, it rests upon the point w. Should the bumper and coupler of oneof the adjoining cars be higher than the other the link-head will falldown into the recess y in the bumper in rear of the point no, and theconnection be as effectually made as in ordinary couplings. In couplings where no bearing-point .r and recess 1/ are used the couplingcould not be so readily made where one car is higher than the otherwithout a change in the form of the link, as the bottom of the couplingwould be dat and allow no play for the head of the link.

The shaft d, to which the wing C is attached, is at each end providedwith a crank, H, weighted on its outer end; and the outer end of eachcrank is, by a chain, m, connected with a shaft, E, placed horizontallyin suitable bearings across the end of the car. Around the center ofthis` shaft is wound another chain, n, which passes up to the top of thecar. By pulling the chain a from the top it revolves the shaft E,winding up the chains m m, and raising the,K cranks H H, thereby alsoraising the win g C and uncoupling the cars. The cranks then fall downagain by the weights on their ends unwinding the chains m m and windingup the chain fn. On each end of the shaft E is a handwheel, J, foruncoupling from either side of the car.

Having thus fully described my invention, what I claim as new, anddesire to secure by 1. The bar D, as constructed, being made longer thanthe spring c, and used in combi Iu. testimony that l claim the foregoingI 11a-tion Withtlle Shaft d, as and for the purpose hereunto set my handthis 19thl dayof No- Set forth. s l vember, 1872.
